HOW TO FIX MY JVC TV

JVC AV-56WP30... | Answered on Dec 29, 2013


I would guess that the top and bottom of the picture is pulled toward the center of the screen as well. This is a convergence problem. If you can solder, you should be able to repair this yourself. If you wish to attempt this repair, please update this and I will provide more details and instructions.

Thanks,
Dan

No you cannot! There is a switch on the convergence pnl for complete convergence. You can make things 10 times worse if you don't know what your doing.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Your convegence has gone out. You can get complete kits with instructions from sites such as www.TvRepairKits.com or just the parts from www.ConvergenceChips.com . If you have never done this before i would suggest going the kit route since it includes step by step photo instructions and support.
